Server Memory Upgrade

This 16 GB DDR4 module operates at 2133 MHz with CL15 latency and 1.20 V standard voltage. ECC UDIMM design provides error correction for data integrity in server and workstation environments. The unbuffered 2Rx8 organisation suits platforms that accept non-registered memory.

Sustained Workload Behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, reducing silent data corruption. Major-brand chips are tested for dependable performance under prolonged load. Standard DDR4 voltage keeps power draw predictable during extended sessions.

Replacement Context

Direct equivalent for Micron MTA18ASF2G72AZ-2G1 and MTA18ASF2G72AZ-2G1A1 part numbers. The jump is worthwhile when a system requires validated ECC unbuffered modules at this speed and capacity. Builders needing registered DIMMs or higher frequencies should verify platform support first.

Questions about this item

How much power does the 1.2V DDR4 module draw during continuous server workloads?

The module operates at the standard DDR4 voltage of 1.2V, keeping power draw low even under sustained 2133 MHz operation in server environments.

What motherboard slot and memory controller features are required for this ECC UDIMM to function?

A 288-pin DDR4 DIMM slot with an ECC-capable memory controller is needed; the module is unbuffered, so no registered-buffer support is required.

Will this 2Rx8 CL15 stick work reliably alongside older DDR4 2133 modules of different rank or latency?

Yes, it follows JEDEC DDR4 2133 CL15 timings at 1.2V, so it can run in mixed-rank populations when the motherboard trains all modules to the same speed and voltage.
